The pet eating fake story reminds me of the Brexit bus. It’s deliberately false so it just sucks up attention as people can’t help but say “there’s no evidence”. But what it has drawn attention to is how many Haitian immigrants have migrated…and that will scare the right people. And all you have to say is “well one person told me it happened to them.” and it doesn’t matter if there’s absolutely no evidence, that’s enough for some.
